WHY IT NEEDS A POLICY

Why move_folder needs a policy

This tool creates or modifies data reversibly—moving a folder changes its parent reference but preserves all data and can be undone by moving it back. It does not irreversibly delete, execute external code, or perform financial operations.

From the tool's definition Tool description states it 'Move[s] a folder under a parent folder' which modifies the organizational structure and hierarchical relationships of stored data. The action changes the state of folders within the system without deleting them.
